ORTHOLOGISTES (RATIONALISTAS) is a hip-hop group with 4 members from a west suburb of Athens, Egaleo. The group was founded in 1999 by two school friends, producer Loop and rapper Sxo. In 2003 two rappers, Zografos and TNT, and a producer, Bayman, joined them.
In 2009, Zografos left the Orthologistes for personal reasons and began working on solo projects. However, Zografos and Orthologistes maintain an affable relationship.
In 2005, they took part in a music contest with 300 participants. It has to be mentioned that they were the only band selected to represent the Hip-Hop scene, but this was only the beginning of their musical way.
In September of 2007, their debut album, “Ap’ to Dromo” (“From the Streets”) was released with massive success all over the country. Through their music, Rationalistas are capable of transforming their thoughts, ideas and experiences into melody and rhythm.
In 2009, TNT released a solo album named “It’s A War” with massive success, which includes collaborations not only with classic rappers such as Keith Murray of Def Squad, Celph Titled of DemiGodz and Big Left of La Coka Nostra, but also with some rising ones from all over the world.
2010 found Orthologistes as the focal point of Greek hip-hop things, while their brand-new album “A Night After the Last Day” (“Mia Nyhta meta tin Teleftea Mera”) placed them on top of the underground music pyramid. It can’t be left unmentioned that in their last album, Rationalistas featured Rakaa of Dilated Peoples on a track entitled “Who, being loved, is poor?”, which was another great step for Greek hip-hop to get developed.
Nowadays, they are performing live all over Greece promoting their new album, while producing music for future projects.
They have taken part in the one and only Greek documentary film about Hip-Hop culture, directed by Nikos Skarentzos and produced by Top Cut, the Greek Film Center and ERT. This film is about to be presented at a few cinemas and at Greek television.
Orthologistes have given an interview to one of the biggest newspapers in Greece named “Eleftherotipia” and to many blogs and Hip-Hop websites.
